Critical Behavior in the Gravitational Collapse of a Scalar Field with Angular Momentum in Spherical Symmetry
Ignacio Olabarrieta, Jason F. Ventrella, Matthew W. Choptuik +1
We study the critical collapse of a massless scalar field with angular momentum in spherical symmetry. In order to mimic the effects of angular momentum we perform a sum of the str…
Scalar field confinement as a model for accreting systems
Miguel Megevand, Ignacio Olabarrieta, Luis Lehner
We investigate the possibility to localize scalar field configurations as a model for black hole accretion. We analyze and resolve difficulties encountered when localizing scalar f…
Head-on collisions of boson stars
C. Palenzuela, I. Olabarrieta, L. Lehner +1
We study head-on collisions of boson stars in three dimensions. We consider evolutions of two boson stars which may differ in their phase or have opposite frequencies but are other…
Critical Collapse of Collisionless Matter in Spherical Symmetry
Ignacio Olabarrieta
We perform a numerical study of the critical regime for the general relativistic collapse of collisionless matter in spherical symmetry. The evolution of the matter is given by the…
